I was a police motorcyclist and was taken off my motorbike by a car driver. It broke both my arms and right leg.
I was obviously decked out like a christmas tree and riding a white and orange motorbike, the size of a car.
In my experience, you can wear whatever you want. But unless the car driver sees you. Its all to no avail.
I do wear a vis vest. But being in the correct position on the road where you can be seen is more important in my opinion.
I always consider myself as part of the traffic and dont hide away in the gutter.
